| description | The invention discloses a leakage-proof detection method, system and device for a railway vehicle water supply system. The method includes the steps: detecting water flow in a water supply system pipeline by a leakage detection switch; triggering a controller to control a water pump to stop working after the leakage detection switch is timed for first delay time when the detected water flow is higher than or equal to a preset flow value; restarting the water pump to work repeatedly for N times after the controller is timed for second delay time. After the water pump is restarted for the N time, the controller is triggered to control the water pump to stop working if the leakage detection switch detects that the water flow is higher than or equal to the preset flow value. The method solves the problem of false alarm of leakage of the water supply system pipeline with long-time continuous flow in the prior art. |
